Understanding Recirculating Kits: Why Go Ductless?
Before we dive into the nuts and bolts, let’s clarify what a recirculating kit does. Unlike ducted range hoods that exhaust air outside your home, a recirculating, or ductless, system filters the air and sends it back into the kitchen.
This is a game-changer for many homes, especially apartments, condos, or kitchens with challenging structural layouts.
How a Recirculating Kit Works
A recirculating range hood doesn’t remove air from your home; it cleans it. Here’s the basic process:
- The hood draws in cooking fumes, steam, and odors.
- A metal grease filter (often aluminum mesh) traps grease particles.
- The air then passes through a specialized charcoal filter (also known as a carbon filter). This is the key component for odor removal.
- Once filtered, the cleaned air is gently released back into your kitchen.
The recirculating kit itself usually consists of these charcoal filters and sometimes a diverter or baffle to redirect the air internally.
When to Choose a Ductless Setup
Opting for a recirculating range hood kit makes sense in several scenarios:
- No Existing Ductwork: This is the most common reason. Running new ducts can be a major, costly renovation.
- Apartments/Condos: Building codes or landlord restrictions might prohibit exterior venting.
- Island Kitchens: Ducting an island hood can be complex and expensive.
- Budget Constraints: Ductless installation often has lower material and labor costs compared to extensive ductwork.
- DIY Friendly: Without complex ducting, the installation becomes a much more manageable project for the average DIYer.
While ducted hoods generally offer superior performance in terms of complete air removal, a well-maintained recirculating system is a highly effective and practical alternative for many kitchens.
Gathering Your Tools and Materials
Preparation is key for any successful DIY project. Before you begin, ensure you have all the necessary tools and the specific recirculating kit for your range hood model.
Essential Tools
You’ll likely need these common workshop tools:

Safety First: Preparing Your Workspace
Safety is paramount at The Jim BoSlice Workshop. Working with electricity and power tools requires caution. Never skip these critical safety steps.
Electrical Safety Precautions
Your range hood is an electrical appliance. Always disconnect power before working on it.
- Turn Off Power: Locate your home’s main electrical panel (breaker box) and switch off the circuit breaker that supplies power to the range hood.
- Verify Power is Off: Use a non-contact voltage tester to confirm no power is flowing to the hood’s wiring. This is a non-negotiable step.
- Clear the Area: Ensure no water or flammable materials are near your workspace.
Workspace Readiness
A well-prepared workspace makes the job easier and safer.
- Clear the Cooktop: Remove all items from your stovetop and surrounding countertop.
- Protect Surfaces: Lay down drop cloths or cardboard to protect your cooktop and counters from scratches or debris.
- Adequate Lighting: Ensure your work area is well-lit.
- Stable Ladder/Stool: Use a sturdy ladder or step stool if you need to reach above the hood. Never stand on your stovetop.
Taking a few extra minutes for safety preparation can prevent accidents and ensure a smooth installation.
how to install recirculating kit for range hood: Step-by-Step Guide
Now, let’s get to the core of the project. This detailed guide will walk you through exactly how to install recirculating kit for range hood, ensuring a smooth process from start to finish. Remember, always refer to your specific range hood’s manual for precise instructions.
Step 1: Disconnecting the Old System (if applicable)
If you’re converting an existing ducted range hood to recirculating, you’ll need to remove the ductwork.
- Remove Grease Filters: Unlatch and remove the existing metal grease filters from the underside of the range hood.
- Disconnect Ductwork: If the hood is currently vented, disconnect the duct pipe from the top or rear of the hood. You may need a screwdriver to loosen clamps or screws.
- Seal the Duct Opening: If you are leaving the duct in place but not using it, seal the opening on the hood with a metal blank-off plate or strong aluminum tape to prevent air leakage and improve efficiency.
If you’re installing a new hood that was never ducted, you can skip the duct removal steps.
Step 2: Installing the Recirculation Blower and Filters
This is where your specific recirculating kit comes into play.
- Locate Filter Housing: Inside the range hood, you’ll find the area where the filters are installed, usually near the fan motor.
- Install Charcoal Filters: The charcoal filters are typically round or rectangular and attach directly to the fan motor assembly or within a designated filter housing. They often twist or clip into place. Follow the kit’s instructions carefully.
- Attach Diverter/Baffle (if included): Some kits include a plastic or metal diverter that helps direct the filtered air back into the kitchen. This usually mounts near the top or front of the fan housing.
- Secure Components: Ensure all filters and diverters are securely fastened. You don’t want them rattling or falling out during operation.
These filters are crucial for odor absorption, so proper installation is key for effective air purification.
Step 3: Adjusting the Damper for Internal Venting
Most range hoods come with a damper (a small flap) that can be set for either external or internal venting.
- Identify the Damper: Look for a flap, usually located at the exhaust opening of the hood, above where the ductwork would connect.
- Set to Recirculate: The damper needs to be positioned so that it blocks the external exhaust opening and directs air internally. Some hoods have a switch or lever to change this setting; others require you to manually position the flap.
- Ensure Free Airflow: Make sure the internal air vents (often slits on the front or top of the hood) are clear and unobstructed, allowing the filtered air to return to the kitchen.
If your hood is designed for both ducted and ductless operation, there will be clear instructions on how to adjust this.
Step 4: Final Assembly and Testing
With the kit installed, it’s time to button everything up and test your work.
- Reinstall Grease Filters: Clip the metal grease filters back into place on the underside of the hood.
- Mount the Hood (if new): If you’re installing a brand-new hood, carefully mount it to the wall or cabinet according to your hood’s specific instructions. Use a level to ensure it’s straight.
- Connect Electrical: If you disconnected wiring or are installing a new hood, connect the electrical wires (black to black, white to white, ground to ground) using wire nuts. Ensure all connections are tight and secure.
- Restore Power: Go back to your electrical panel and flip the circuit breaker back on.
- Test the Hood: Turn on your range hood. Listen for the fan, check that the lights work, and feel for air being drawn in and then gently expelled back into the kitchen from the designated recirculation vents.
A successful test means you’ve mastered how to install recirculating kit for range hood!
Troubleshooting Common Installation Issues
Even the most careful DIYer can encounter a snag. Here are a few common issues and their solutions when learning how to install recirculating kit for range hood.
Insufficient Airflow
If the fan seems weak or isn’t drawing air effectively:
- Check Filters: Ensure both grease and charcoal filters are correctly seated and not clogged. New filters are often stiff, ensure they are fully in place.
- Damper Position: Double-check that the internal damper is correctly set to recirculate and not partially blocking the internal vents.
- Obstructions: Look for any packaging material or debris that might be blocking the fan or the internal air vents.
Persistent Odors
If cooking odors aren’t being effectively removed:
- Charcoal Filters: Confirm the charcoal filters are installed correctly and are the right type for your hood. If they are old, they may need replacing.
- Filter Seating: Ensure the charcoal filters are tightly sealed, allowing no air to bypass them.
- Hood Size/Power: Consider if your hood’s CFM (Cubic Feet per Minute) rating is adequate for your cooktop and cooking habits. For heavy cooking, a more powerful hood might be needed.
Noise Concerns
Excessive noise can be irritating:
- Loose Components: Check that all filters, brackets, and internal components are securely fastened. Loose parts can vibrate.
- Mounting: Ensure the range hood itself is securely mounted to the wall or cabinet. Poor mounting can cause vibrations to amplify.
- Fan Blades: Very rarely, a fan blade might be bent or out of balance. If the noise is significant and persistent, contact the manufacturer.
Most issues are minor and easily resolved with a quick check of the installation steps and components.
Maintaining Your Ductless Range Hood
A recirculating range hood is only as effective as its filters. Regular maintenance is crucial for optimal performance and air quality.
Filter Replacement Schedule
This is the most important maintenance task for a ductless hood.
- Charcoal Filters: These cannot be cleaned and must be replaced. Most manufacturers recommend replacing them every 3-6 months, depending on cooking frequency. Heavy frying will require more frequent changes.
- Grease Filters: The metal mesh grease filters should be cleaned regularly – ideally every month or two. They can usually be washed by hand with hot, soapy water or in a dishwasher.
Neglecting filter replacement will significantly reduce your hood’s ability to remove odors and grease, making all your hard work on how to install recirculating kit for range hood less effective.
Cleaning and Care
Beyond filters, general cleaning keeps your hood looking good and working efficiently.
- Exterior: Wipe down the exterior of your hood regularly with a mild, non-abrasive cleaner.
- Internal Vents: Periodically wipe down the internal air vents where the filtered air re-enters the kitchen.
- Fan Blades: If accessible and safe to do so with power disconnected, gently wipe down the fan blades to remove any accumulated grease.
Consistent maintenance will extend the life of your range hood and keep your kitchen smelling fresh.
Frequently Asked Questions About Recirculating Range Hoods
Here are some common questions DIYers ask about ductless range hoods and their kits.
Are recirculating range hoods as good as ducted ones?
While ducted hoods offer superior performance by removing air completely from your home, recirculating hoods are highly effective at filtering grease and odors, especially with proper filter maintenance. They are an excellent solution when external venting is not possible.
How often do I need to replace charcoal filters?
Most manufacturers recommend replacing charcoal filters every 3 to 6 months. This can vary based on your cooking habits; if you cook frequently or do a lot of frying, you might need to replace them more often.
Can I convert any range hood to recirculating?
No, not every range hood can be converted. Most modern range hoods are designed for both ducted and ductless operation and will have an optional recirculating kit available. Always check your specific range hood model’s manual or manufacturer’s website to confirm compatibility.
Do recirculating range hoods help with steam and moisture?
